Why Roof Box Wind Noise Happens in FORTHING Vehicles
Adding a roof box to your FORTHING T5 EVO, S7, or M4 increases storage—but often introduces an irritating side effect: wind noise. As air flows over the vehicle, it hits the box and rack system, causing:
-
Turbulent air currents
-
Whistling or droning sounds
-
Reduced fuel efficiency
-
Driver fatigue on long trips
The good news? There are simple, proven upgrades and modifications that reduce wind resistance and restore quiet comfort.
Top Strategies for FORTHING Roof Box Wind Noise Reduction
Below are practical, vehicle-compatible ways to reduce aerodynamic drag and sound without sacrificing function.
1. Use an Aerodynamic Roof Box Design
Not all boxes are equal. Choose a model with a teardrop shape and tapered rear end. At FORTHINGPARTS, our OEM-compatible roof boxes are wind-tunnel tested.
2. Lower the Box Height
The further your box is from the roof, the more turbulence it creates. Use low-profile mounting kits that hug the roofline to decrease noise by 20–30%.
3. Install Wind Fairings or Deflectors
A wind fairing is a curved shield installed at the front of your roof rack. It redirects airflow over the box, preventing it from hitting sharp corners or rails.
| Benefit | Wind Fairing Installation |
|---|---|
| Noise reduction | ✅ 30–50% decrease |
| Better fuel economy | ✅ Up to 10% improvement |
| Easy to install | ✅ No drilling required |
4. Check Rack Alignment
Misaligned crossbars can trap air. Keep bars parallel to each other and perpendicular to the road.
5. Tighten All Mounting Points
Loose clamps or brackets vibrate at high speeds. Recheck all mounting hardware and use rubber padding to absorb noise.

DIY Installation Tips for Quiet Performance
You don’t need a technician to install your noise-reduction gear. Follow these steps for optimal results.
Installation Checklist:
-
Measure box and crossbar spacing
-
Attach fairing using included clamps
-
Use foam spacers under roof box brackets
-
Test fit before highway speeds
-
Drive at 80km/h and listen for changes
Pro Tip: Add weatherstripping between the box and base rails for an extra soundproof layer.
How Wind Noise Affects Driving Experience
Wind noise is more than just annoying—it can negatively impact driving quality:
-
Cognitive fatigue on long drives
-
Increased cabin volume, making conversations harder
-
Lower fuel efficiency due to drag
-
Wear and tear on box mounts and crossbars
Investing in FORTHING roof box wind noise reduction is not just about comfort—it’s about long-term performance and efficiency.

FAQs – FORTHING Roof Box Wind Noise Reduction
Will a wind fairing eliminate all roof box noise?
No, but it can reduce it by up to 50%, especially at speeds above 80 km/h.
Does lowering the roof box really help?
Yes. A lower center of gravity reduces turbulence and improves vehicle handling.
Are wind deflectors universal or model-specific?
We offer model-specific options at FORTHINGPARTS to ensure tight fit and proper airflow.
What material are OEM wind deflectors made of?
They’re typically polycarbonate or aluminum alloy with rubber feet—weather-resistant and vibration-absorbing.
Is it normal for roof box noise to increase at high speed?
Yes, but excessive noise suggests poor fitment or the need for aerodynamic upgrades.
Can I combine multiple noise-reduction methods?
Absolutely! Fairings, spacers, and low-profile racks work best when used together.
